# Log user impersonation

Configure **glide.sys.log\_impersonation** to control if user-impersonating events are logged in your instance.

If **glide.sys.log\_impersonation** is not set to the recommended value of **true**, then user-impersonating events are no longer logged.

Ensure that the property **glide.sys.log\_impersonation** exists in the System Properties \[sys\_properties\] table and is set to **true**. If the property does not appear in the System Properties \[sys\_properties\] table, add a new record.
